The calculated max. HR (heart rate) forms the basis for deter-
mining the upper and lower limits of your preferred training zone. 
Selecting and setting the training zone is done in the “Settings //
User // Train. Zone” menu. Depending on your personal targets, 
you can choose to activate one of the following training zones in 
the PC 25.10.

1. Fat Burner Zone: k approx. 55–70 % of hr max.

When training at a lower intensity and hence longer period, 
a bigger percentage of fat than carbohydrate is used to provide 
energy. Therefore people who primarily want to reduce their 
weight and burn fat should train in this area. The recommended 
training period is 45-90 min.

Beginners, who have not done any sport for a long time, should 
also start training in this area of intensity at first. This significantly 
reduces the danger of over-exertion and the associated health 
risks.

2. Fitness Zone: k approx. 70–80 % of hr max. 

Heart-circulation training is predominantly used to improve 
aerobic performance.

3. personal Zone:
PC 25.10 also gives you the opportunity to set your own 
training zone. To do this you change the upper and lower limits 
in the “Settings //User // Train. Zone” menu option using the 
navigation button k CHANGE.
